    What Is Microsoft Security Copilot?

    Microsoft Security Copilot is a generative AI-powered security analysis tool built on top of OpenAI’s GPT-4 model, enriched with Microsoft’s proprietary security-specific models and a massive threat intelligence graph that processes 78 trillion security signals every day. Unlike general-purpose AI assistants, Security Copilot is purpose-built for cybersecurity workflows: it understands the language of threat actors, MITRE ATT&CK techniques, Common Vulnerabilities and Exposures (CVEs), and the operational context of enterprise security operations.

    The platform operates through a prompt-based interface where analysts interact with their entire security estate using natural language. Instead of manually pivoting across multiple consoles, writing KQL queries from scratch, or correlating alerts across disparate tools, analysts describe what they need and Security Copilot synthesizes responses from across the Microsoft security ecosystem and third-party sources.

    How Security Copilot Processes a Query

    When an analyst submits a prompt, the system orchestrates a sophisticated multi-step pipeline. The orchestration engine first classifies the intent, then selects the appropriate plugins and data sources, executes the necessary queries, and synthesizes the results into a coherent response grounded in real security telemetry.

    Architecture Detail: Security Copilot maintains a session-based memory model. Each investigation session creates a “pinboard” where all prompts and responses are preserved, allowing analysts to build context over the course of a complex investigation. Sessions can be shared across the SOC team for collaborative analysis.

    Core Capabilities

    Incident Summarization

    One of the most impactful capabilities is automated incident summarization. Security Copilot can take a complex, multi-alert incident spanning hours or days and distill it into a clear narrative that includes the attack timeline, affected assets, techniques used, and current containment status. This transforms what traditionally takes a senior analyst 30-60 minutes into a task completed in seconds.

    // Example: Incident Summarization Prompt
    
    Prompt: "Summarize incident #4892 including the full attack
    timeline, all affected entities, MITRE ATT&CK techniques
    identified, and current containment status."
    
    // Security Copilot Response (summarized):
    Incident #4892 - Multi-Stage Ransomware Attack
    Severity: High | Status: Active | Duration: 14 hours
    
    Timeline:
      03:22 UTC - Initial access via phishing email (T1566.001)
      03:45 UTC - Credential harvesting from user endpoint (T1003)
      04:12 UTC - Lateral movement to file server (T1021.002)
      06:30 UTC - Data staging on compromised server (T1074)
      08:15 UTC - Encryption initiated on 3 endpoints (T1486)
    
    Affected Entities:
      Users: jdoe@contoso.com, admin-svc@contoso.com
      Devices: WKS-1042, SRV-FILES-02, SRV-FILES-03
      Mailboxes: 1 compromised
    
    Containment: 2 of 3 affected devices isolated

    Threat Intelligence Analysis

    Security Copilot provides deep threat intelligence analysis by correlating indicators of compromise (IOCs) against Microsoft’s global threat intelligence graph, which aggregates data from billions of endpoints, cloud workloads, email messages, and identity signals worldwide. Analysts can query specific indicators and receive enriched context instantly.

    // Example: Threat Intelligence Query
    
    Prompt: "What is known about the threat actor group
    associated with IP 203.0.113.42? Include their TTPs,
    known campaigns, and recommended mitigations."
    
    // Security Copilot correlates across:
      Microsoft Threat Intelligence - Actor profiles & campaigns
      Defender TI - Infrastructure mapping & IOC enrichment
      Open-source feeds - STIX/TAXII, abuse databases
      Tenant telemetry - Historical interactions with the IP

    Script and Command Analysis

    Security analysts frequently encounter obfuscated scripts during incident response, from PowerShell download cradles to encoded batch files. Security Copilot can deobfuscate, analyze, and explain these scripts in plain language, identifying the intent and potential impact without requiring the analyst to be an expert in every scripting language.

    // Example: Script Analysis Prompt
    
    Prompt: "Analyze this obfuscated PowerShell command found on
    endpoint WKS-1042 and explain what it does, its risk
    level, and which MITRE techniques it maps to."
    
    // Security Copilot deobfuscates and explains:
    Analysis Result:
      Purpose: Downloads and executes a second-stage payload
      Risk Level: Critical
      Techniques: T1059.001 (PowerShell), T1105 (Ingress Tool Transfer)
      Indicators: Connects to external C2 infrastructure
      Recommendation: Isolate endpoint, block domain at proxy

    KQL Query Generation

    Kusto Query Language (KQL) is the backbone of Microsoft’s security analytics across Sentinel, Defender, and Log Analytics. Security Copilot translates natural language requests into production-ready KQL queries, dramatically lowering the barrier for junior analysts while accelerating query development for experienced ones.

    // Prompt: "Write a KQL query to find all successful logins
    // from impossible travel locations in the last 7 days"
    
    // Generated KQL:
    let timeRange = 7d;
    let maxTravelSpeedKmH = 900;
    SigninLogs
    | where TimeGenerated > ago(timeRange)
    | where ResultType == "0"  // Successful logins only
    | extend Latitude = toreal(LocationDetails.geoCoordinates.latitude)
    | extend Longitude = toreal(LocationDetails.geoCoordinates.longitude)
    | sort by UserPrincipalName asc, TimeGenerated asc
    | serialize
    | extend PrevLat = prev(Latitude), PrevLon = prev(Longitude)
    | extend PrevTime = prev(TimeGenerated)
    | extend PrevUser = prev(UserPrincipalName)
    | where UserPrincipalName == PrevUser
    | extend DistanceKm = geo_distance_2points(
        Longitude, Latitude, PrevLon, PrevLat) / 1000
    | extend TimeDiffHours = datetime_diff(
        'hour', TimeGenerated, PrevTime)
    | where TimeDiffHours > 0
    | extend SpeedKmH = DistanceKm / TimeDiffHours
    | where SpeedKmH > maxTravelSpeedKmH
    | project TimeGenerated, UserPrincipalName,
        IPAddress, Location, DistanceKm, SpeedKmH

    Vulnerability Assessment

    Security Copilot integrates with Defender Vulnerability Management to provide contextual vulnerability assessments. Rather than presenting a flat list of CVEs, it prioritizes vulnerabilities based on your specific environment, considering exploitability, asset criticality, exposure level, and active threat actor campaigns targeting those vulnerabilities.

    Pro Tip: Combine vulnerability assessment with threat intelligence prompts. Ask Security Copilot: “Which of our unpatched vulnerabilities are being actively exploited by threat actor groups currently targeting our industry?” This contextualizes risk beyond CVSS scores alone.

    Integration with Microsoft Security Products

    Security Copilot draws its power from deep native integration with Microsoft’s security product suite. Each product connection exposes specific capabilities through plugins, allowing the AI to query, correlate, and act across the entire security estate.

    Microsoft Defender XDR

    The Defender XDR integration is the most comprehensive, providing access to incidents, alerts, device inventories, email analysis, and automated investigation data. Security Copilot surfaces directly within the Defender XDR portal, offering contextual assistance alongside your existing workflow.

    // Defender XDR Integration Prompts
    
    Incident Analysis:
    "Show me all high-severity incidents from the last 24 hours
    that involve lateral movement techniques."
    
    Email Threat Analysis:
    "Analyze the email headers and attachments from the phishing
    campaign targeting our finance department this week."
    
    Device Investigation:
    "What processes were running on device WKS-1042 at the time
    of the initial compromise? Highlight any anomalous activity."
    
    Automated Response:
    "What automated investigation actions have been taken on
    incident #4892 and what is the current remediation status?"

    Microsoft Sentinel

    The Sentinel integration connects Security Copilot to your SIEM data lake, enabling natural language searches across log sources, automated hunting query generation, and analytics rule creation. Analysts can ask questions across terabytes of log data without writing a single line of KQL themselves.

    // Prompt: "Search Sentinel logs for any data exfiltration
    // indicators from the compromised user account in the
    // last 48 hours"
    
    // Generated Sentinel Hunting Query:
    let compromisedUser = "jdoe@contoso.com";
    let lookback = 48h;
    union
      (OfficeActivity
        | where TimeGenerated > ago(lookback)
        | where UserId =~ compromisedUser
        | where Operation in ("FileDownloaded", "FileSyncDownloadedFull")
        | summarize DownloadCount = count(),
            TotalSize = sum(OfficeObjectId) by bin(TimeGenerated, 1h)),
      (CommonSecurityLog
        | where TimeGenerated > ago(lookback)
        | where SourceUserName =~ compromisedUser
        | where DeviceAction == "Allow"
        | where SentBytes > 50000000  // 50MB+ transfers
        | project TimeGenerated, DestinationIP,
            DestinationPort, SentBytes)
    | sort by TimeGenerated desc

    Microsoft Intune

    The Intune plugin gives Security Copilot visibility into device compliance, configuration policies, and application management. This is particularly valuable during incident response when you need to quickly assess whether a compromised device meets your security baseline or identify policy gaps that may have contributed to the breach.

    // Intune Integration Prompts
    
    Compliance Check:
    "What is the compliance status of device WKS-1042?
    List any policy violations and when they were last evaluated."
    
    Policy Gap Analysis:
    "Which devices in the Finance department are missing
    BitLocker encryption or have outdated antivirus definitions?"
    
    App Risk Assessment:
    "List all unmanaged applications installed on devices
    owned by users involved in incident #4892."

    Microsoft Entra ID

    Entra ID integration surfaces identity-centric insights: risky user profiles, anomalous sign-in patterns, conditional access policy evaluations, and privilege escalation indicators. For identity-driven attacks, which account for the vast majority of breaches, this integration is critical.

    // Entra ID Integration Prompts
    
    Risky User Analysis:
    "Show me the complete risk profile for user jdoe@contoso.com
    including recent sign-in anomalies, risk detections, and
    any conditional access policy failures."
    
    Privilege Audit:
    "List all users who were granted Global Administrator or
    Security Administrator roles in the past 30 days, including
    who approved the assignment."
    
    Access Review:
    "Which service principals have excessive permissions and
    have not been used in the last 90 days?"

    Microsoft Purview

    The Purview integration connects data governance and compliance insights to the security workflow. Security Copilot can assess data exposure risks, identify sensitive data involved in security incidents, and generate compliance impact reports for regulatory requirements.

    Integration Depth: Security Copilot’s embedded experience within Defender XDR, Sentinel, and Intune means analysts do not need to switch to a separate portal. The Copilot pane appears directly within each product’s investigation workflow, maintaining context and reducing pivot time between tools.

    Promptbooks: Automated Investigation Workflows

    Promptbooks are one of Security Copilot’s most powerful features for operationalizing institutional knowledge. A promptbook is an ordered sequence of prompts that execute together, creating a repeatable investigation workflow. They function as automated runbooks powered by natural language, enabling SOC teams to standardize investigation procedures while leveraging AI at each step.

    Pre-Built Promptbooks

    Microsoft ships a library of pre-built promptbooks covering common security scenarios. These serve as starting points that teams can customize for their specific environment and procedures.

    PromptbookPurposeKey Steps
    Incident InvestigationFull incident triage and analysisSummarize incident, map ATT&CK, identify scope, recommend remediation
    Vulnerability ImpactCVE risk assessmentDescribe CVE, check exposure, identify affected assets, prioritize patching
    Suspicious Script AnalysisDeobfuscate and assess scriptsDecode script, explain behavior, assess risk, map techniques
    User CompromiseIdentity-based investigationReview sign-ins, check risk detections, audit permissions, timeline
    Threat Actor ProfileAdversary intelligenceIdentify group, map TTPs, assess targeting, recommend defenses
    Compliance AssessmentRegulatory impact analysisClassify data involved, map to regulations, generate report

    Creating Custom Promptbooks

    Custom promptbooks allow security teams to encode their specific investigation methodologies, compliance requirements, and organizational context into reusable workflows. Each step in a promptbook can reference outputs from previous steps, building a chain of analysis.

    // Custom Promptbook: Phishing Investigation
    {
      "name": "Phishing Campaign Investigation",
      "description": "Comprehensive phishing analysis workflow",
      "tags": ["phishing", "email", "incident-response"],
      "prompts": [
        {
          "step": 1,
          "prompt": "Analyze the email headers and identify
            the true sender, originating infrastructure, and
            any authentication failures (SPF/DKIM/DMARC)."
        },
        {
          "step": 2,
          "prompt": "Check Microsoft Threat Intelligence for
            the sender domain and any URLs found in step 1.
            Is this associated with a known campaign?"
        },
        {
          "step": 3,
          "prompt": "How many users in our organization received
            similar emails? List all recipients and whether
            they clicked any links or opened attachments."
        },
        {
          "step": 4,
          "prompt": "For any users who interacted with the
            phishing email, check their Entra ID sign-in
            logs for anomalies in the last 24 hours."
        },
        {
          "step": 5,
          "prompt": "Generate a summary report of this phishing
            campaign including IOCs, affected users, current
            risk level, and recommended remediation steps."
        }
      ]
    }
    Best Practice: Build promptbooks that mirror your existing incident response playbooks. This creates a natural adoption path for SOC analysts: the workflow structure remains familiar, but each step is now augmented with AI-powered analysis. Start with your top five most common incident types and expand from there.

    Custom Plugins: Extending Security Copilot

    Security Copilot’s plugin architecture allows organizations to connect custom data sources, proprietary threat intelligence feeds, and internal tools. Plugins are defined using an OpenAPI specification, making them accessible to any team with REST API experience. This extensibility transforms Security Copilot from a Microsoft-centric tool into a unified security analysis platform.

    Plugin Types

    • Microsoft plugins – Pre-built connections to Microsoft security products (Defender, Sentinel, Intune, Entra ID, Purview)
    • Third-party plugins – Integrations from partners like ServiceNow, Splunk, and CrowdStrike
    • Custom plugins – Organization-built plugins connecting internal APIs, threat feeds, and proprietary data sources
    • Website plugins – Plugins that can ingest and reason over content from specific websites or documentation portals

    Building a Custom Plugin

    A custom plugin is defined through an OpenAPI manifest that describes the API endpoints Security Copilot should call, the parameters it accepts, and the response format. The manifest includes semantic descriptions that help the AI understand when and how to use the plugin.

    # Custom Plugin Manifest: Internal Threat Intel Feed
    openapi: "3.0.0"
    info:
      title: "Contoso Threat Intelligence"
      description: "Internal threat intel feed with IOCs,
        actor profiles, and campaign tracking."
      version: "1.0.0"
    servers:
      - url: "https://threatintel.contoso.com/api/v1"
    paths:
      /ioc/lookup:
        get:
          operationId: "lookupIOC"
          summary: "Look up an indicator of compromise"
          description: "Searches the internal threat
            intelligence database for information about
            a specific IOC (IP, domain, hash, URL)."
          parameters:
            - name: "indicator"
              in: "query"
              required: true
              schema:
                type: "string"
              description: "The IOC value to search for"
            - name: "type"
              in: "query"
              schema:
                type: "string"
                enum: ["ip", "domain", "hash", "url"]
          responses:
            "200":
              description: "IOC enrichment data"
      /campaigns/active:
        get:
          operationId: "getActiveCampaigns"
          summary: "List active threat campaigns"
          description: "Returns currently active threat
            campaigns targeting our organization."
    Security Consideration: Custom plugins execute API calls with the permissions of the authenticated user. Ensure your plugin APIs implement proper authentication (OAuth 2.0 or API key), apply least-privilege access controls, and log all queries for audit purposes. Never expose internal APIs without proper network segmentation and rate limiting.

    Security Compute Units (SCUs): Pricing and Capacity

    Security Copilot uses a consumption-based pricing model built around Security Compute Units (SCUs). Unlike seat-based licensing, SCUs represent processing capacity, meaning you pay for the compute resources consumed during AI-powered analysis rather than per-user. This model provides flexibility but requires careful capacity planning.

    Understanding SCU Consumption

    Operation TypeApproximate SCU CostExample
    Simple queryLowSingle-source lookups, IOC enrichment
    Incident summaryMediumMulti-source correlation, timeline generation
    Complex investigationHighFull promptbook execution, deep analysis
    Report generationMedium-HighCompliance reports, executive summaries
    KQL generation + executionMediumQuery construction and result analysis

    Capacity Planning Guidelines

    SCUs are provisioned in units that you can scale up or down based on demand. Microsoft recommends starting with a baseline allocation and monitoring consumption patterns over the first 30 days. Key factors that influence SCU requirements include the size of your SOC team, the volume of incidents processed, and how extensively promptbooks and custom plugins are used.

    // SCU Capacity Planning Framework
    
    Small SOC (3-5 analysts)
      Baseline:    3 SCUs provisioned
      Use Cases:   Ad-hoc incident investigation
      Frequency:  10-20 sessions/day
      Budget:     Suitable for targeted adoption
    
    Medium SOC (10-20 analysts)
      Baseline:    6-10 SCUs provisioned
      Use Cases:   Regular incident triage + threat hunting
      Frequency:  50-100 sessions/day
      Budget:     Monitor peaks during active incidents
    
    Large SOC / MSSP (50+ analysts)
      Baseline:    15+ SCUs provisioned
      Use Cases:   Full SOC integration + automated workflows
      Frequency:  200+ sessions/day
      Budget:     Consider reserved capacity for predictability
    Cost Management: Use Azure Monitor to track SCU consumption in real time. Set up alerts for unusual consumption spikes and establish usage policies that define when Security Copilot should be used versus traditional investigation methods. The usage dashboard within the Security Copilot settings provides per-user and per-session consumption breakdowns.

    Real-World Use Cases

    Use Case 1: Accelerated Incident Response

    A multinational enterprise detected suspicious activity on a Friday evening when only a junior analyst was on shift. Using Security Copilot, the analyst executed a pre-built incident investigation promptbook that automatically summarized the multi-stage attack, identified all compromised accounts, mapped the adversary’s lateral movement path, and generated containment recommendations. What would have required escalation to a senior analyst and hours of manual investigation was completed in under 15 minutes.

    // Incident Response Workflow with Security Copilot
    
    Phase 1: Detection & Triage (minutes 0-3)
      Prompt: "Summarize the latest high-severity incident
      and assess whether this is a true positive."
      → AI correlates alerts, confirms ransomware precursor activity
    
    Phase 2: Scoping (minutes 3-7)
      Prompt: "Identify all entities connected to this
      incident. Map the lateral movement path and
      highlight any domain admin accounts involved."
      → Complete blast radius identified across 12 assets
    
    Phase 3: Containment (minutes 7-10)
      Prompt: "Recommend containment actions. Which devices
      should be isolated and which accounts should be
      disabled to stop lateral movement?"
      → Prioritized containment actions generated
    
    Phase 4: Communication (minutes 10-15)
      Prompt: "Generate an executive summary of this incident
      suitable for the CISO and legal team, including
      potential regulatory notification requirements."
      → Board-ready report produced automatically

    Use Case 2: Proactive Threat Hunting

    A threat intelligence team received an industry advisory about a new campaign targeting financial services. Using Security Copilot, they translated the advisory’s IOCs and TTPs into hunting queries across their Sentinel workspace, identified potential early indicators within their environment, and created detection rules to catch future variations of the attack.

    Use Case 3: Compliance and Audit Reporting

    During a SOC 2 audit, the security team needed to demonstrate their incident response capabilities and mean time to respond (MTTR) metrics. Security Copilot generated comprehensive reports from historical incident data, calculated response time metrics, and produced summaries of containment effectiveness across the audit period, reducing report preparation from days to hours.

    Security and Governance Considerations

    Data Residency: Security Copilot processes your prompts and tenant data within the Microsoft cloud. At GA, data processing occurs within your selected geography (US or EU). However, for certain threat intelligence enrichment tasks, data may be sent to global services. Review Microsoft’s data handling documentation to ensure alignment with your data sovereignty requirements before deployment.
    Role-Based Access: Security Copilot integrates with Microsoft Entra ID roles. Access is controlled through two primary roles: Security Copilot Owner (can manage settings, plugins, and SCU capacity) and Security Copilot Contributor (can create and run sessions). Always follow least-privilege principles when assigning these roles.
    Audit Trail: Every Security Copilot session is logged and auditable. Enable diagnostic logging to your Sentinel workspace to maintain a complete record of all AI-assisted investigations. This is essential for compliance frameworks that require documentation of investigation procedures and tools used.

    Getting Started: Deployment Checklist

    Deploying Security Copilot requires careful planning across licensing, infrastructure, and organizational readiness. Follow this checklist to ensure a smooth onboarding process.

    1. Verify licensing prerequisites. Security Copilot requires Microsoft Entra ID P1 or P2 in your tenant, plus an active Azure subscription for SCU provisioning. Ensure your Microsoft 365 and Defender licensing tiers support the integration points you plan to use.
    2. Provision Security Compute Units. Navigate to the Azure portal, create a Security Copilot resource, and provision your initial SCU allocation. Start with the minimum recommended for your SOC size and scale based on observed consumption.
    3. Configure Entra ID roles. Assign the Security Copilot Owner role to your security engineering lead and Contributor roles to SOC analysts. Ensure Conditional Access policies allow access from SOC workstations and approved locations.
    4. Enable Microsoft security product plugins. Activate the Defender XDR, Sentinel, Intune, Entra ID, and Purview plugins. Each plugin requires the appropriate product license and service connectivity. Validate data flow by running a test prompt against each product.
    5. Connect third-party and custom plugins. If your SOC uses non-Microsoft tools, deploy the relevant third-party plugins or create custom OpenAPI-based plugins for internal data sources. Test authentication flows and response formats.
    6. Build initial promptbooks. Convert your top five most common incident types into Security Copilot promptbooks. Test them against recent incidents to validate accuracy and completeness. Iterate based on analyst feedback.
    7. Establish usage policies and governance. Define when analysts should use Security Copilot versus traditional methods, set SCU budget thresholds, and create guidelines for handling AI-generated outputs (human review requirements, confidence thresholds, escalation criteria).
    8. Enable audit logging and monitoring. Route Security Copilot diagnostic logs to your Sentinel workspace. Create dashboards for SCU consumption, session activity, and adoption metrics. Set up alerts for unusual usage patterns.
    9. Conduct SOC team training. Run tabletop exercises using Security Copilot for incident response scenarios. Train analysts on effective prompt engineering, promptbook creation, and the limitations of AI-generated analysis. Emphasize that AI outputs require human validation.
    10. Measure and iterate. Track MTTR (mean time to respond), MTTI (mean time to investigate), and analyst satisfaction metrics before and after deployment. Use these baselines to demonstrate ROI and identify areas for workflow optimization.

  • Copilot Studio

    What if you could build an AI-powered assistant for your company — one that answers questions, automates tasks, and connects to your internal systems — without writing a single line of code? That’s exactly what Microsoft Copilot Studio delivers, and it’s more accessible than you might think.

    This guide walks you through what Copilot Studio can do, how to build your first copilot, and where it fits in the broader Microsoft AI ecosystem.


    What is Copilot Studio?

    Copilot Studio (formerly Power Virtual Agents) is Microsoft’s low-code platform for creating custom AI assistants — called copilots. These copilots can:

    • Answer questions using your own data (SharePoint, websites, uploaded files).
    • Follow conversation flows with branching logic, conditions, and variables.
    • Take actions by calling Power Automate flows, APIs, or connectors.
    • Operate across channels: Microsoft Teams, websites, Facebook, Slack, and more.

    The key difference from a simple chatbot: Copilot Studio combines generative AI (GPT-powered answers grounded in your data) with deterministic topics (structured conversation paths you control). You get the flexibility of AI with the reliability of predefined logic.

    Generative answers vs. authored topics

    Copilot Studio gives you two ways to handle user questions:

    ApproachHow it worksBest for
    Generative answersThe copilot searches your data sources and generates a natural language response using AIFAQs, knowledge bases, documentation, general inquiries
    Authored topicsYou design a specific conversation flow with triggers, questions, conditions, and actionsProcesses that require specific steps, data collection, system integrations

    In practice, most copilots use both. Generative answers handle the broad “long tail” of questions, while authored topics manage critical processes where you need full control over the experience.

    What can you build?

    IT help desk assistant

    A copilot that answers common IT questions (“How do I reset my password?”, “How do I connect to the VPN?”) using your internal documentation, and escalates to a human agent when needed.

    HR onboarding companion

    New employees ask about benefits, policies, and procedures. The copilot pulls answers from SharePoint and guides them through onboarding tasks step by step.

    Customer support agent

    Deploy a copilot on your website that handles product questions, checks order status (via API calls), and creates support tickets when it can’t resolve an issue.

    Internal operations bot

    A Teams-based copilot that lets employees submit vacation requests, check remaining PTO, or look up project status — all through natural conversation.

    Building your first copilot

    Step 1: Access Copilot Studio

    1. Go to copilotstudio.microsoft.com.
    2. Sign in with your Microsoft 365 or Power Platform account.
    3. Click Create in the left menu and select New copilot.

    Step 2: Describe your copilot

    Copilot Studio lets you set up your assistant by simply describing what it should do. Provide:

    • A name (e.g., “Contoso IT Helper”).
    • A description of its purpose and behavior.
    • Instructions that guide tone and boundaries (e.g., “Answer only IT-related questions. Be concise and professional. If unsure, suggest contacting the IT help desk.”).

    Step 3: Add knowledge sources

    This is where your copilot gets its intelligence. Add one or more data sources:

    • SharePoint sites: point to your documentation libraries.
    • Public websites: the copilot will crawl and index the content.
    • Uploaded files: PDFs, Word documents, and other files.
    • Dataverse tables: structured business data from your Power Platform environment.

    Once connected, the copilot uses generative AI to answer questions based on these sources — no training required.

    Step 4: Create an authored topic

    For specific processes, create a topic:

    1. Go to the Topics tab and click Add a topic.
    2. Define trigger phrases (e.g., “reset my password”, “I can’t log in”, “password help”).
    3. Build the conversation flow using the visual editor:
      • Ask questions to collect information.
      • Add conditions to branch the conversation.
      • Call a Power Automate flow to take action (e.g., send a password reset link).
      • Display a message confirming the action was completed.

    Step 5: Test and publish

    Use the built-in Test copilot panel to simulate conversations. Once satisfied:

    1. Click Publish in the top menu.
    2. Choose your channel: Microsoft Teams, a website embed (via iframe), or external channels like Slack or Facebook.
    3. For Teams, your copilot appears as a chat app that users can find in the Teams app store.

    Connecting to external systems

    Copilot Studio integrates with 1,000+ connectors through Power Automate. Common integrations include:

    • ServiceNow: create and update support tickets.
    • Salesforce: look up customer information and log activities.
    • SAP: check inventory or order status.
    • Custom APIs: call any REST API using the HTTP connector.
    • Azure OpenAI: run advanced AI prompts beyond the built-in generative capabilities.

    These integrations turn your copilot from a Q&A bot into a genuine virtual assistant that gets things done.

    Copilot Studio vs. Azure Bot Service

    FeatureCopilot StudioAzure Bot Service
    Target audienceBusiness users, citizen developersProfessional developers
    Code requiredNo (low-code visual editor)Yes (C#, JavaScript, Python)
    Built-in AIGenerative answers includedManual integration with AI services
    Connectors1,000+ via Power AutomateCustom code for integrations
    Best forBusiness scenarios, fast deploymentComplex, custom-coded bots

    If you need a copilot up and running fast and your team doesn’t have dedicated developers, Copilot Studio is the right choice. For deeply custom scenarios requiring full code control, Azure Bot Service gives you maximum flexibility.

    Licensing and pricing

    Copilot Studio is licensed per tenant with a capacity-based model:

    • Copilot Studio license: includes 25,000 messages per month per tenant.
    • Additional message packs can be purchased for higher volumes.
    • Microsoft 365 users with certain plans get limited Copilot Studio capabilities as part of their license.
    • A free trial is available at copilotstudio.microsoft.com — no credit card required.

    A “message” is a single interaction (user message + copilot response). Generative AI responses consume more messages than simple authored topic responses.

    Next steps

    1. Start a free trial at copilotstudio.microsoft.com and build your first copilot in under 30 minutes.
    2. Connect a SharePoint site as a knowledge source to see generative answers in action.
    3. Create one authored topic for a specific process your team handles frequently.
    4. Explore the official docs: learn.microsoft.com/microsoft-copilot-studio

    Conclusion

    Copilot Studio puts AI assistant creation in the hands of business teams. You don’t need to be a developer to build a copilot that answers employee questions, automates routine processes, and integrates with the tools your organization already uses. With generative AI handling the broad questions and authored topics managing critical workflows, it strikes the right balance between intelligence and control.
